COKCLUSIONS AND SUGGESTIONS 



There is but one conclusion. Where soil is badly infested 

 with witch-grass it is advisable to use the hoe if the horse cul- 

 tivator is inadequate in destroying it. 



In this experiment the increased yield paid for the labor 

 many times. If instead of planting in drills, the method were 

 changed to that of planting in hills, the cultivator could be 

 run both ways, and practically all weeds and witch-grass could 

 be destroyed.
